When dividing 4 by 977, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 977

Advancing to step 2:
977 goes into 42 0 times with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 42 and we're left with 42.
Append the next digit (9) from the dividend to 42 and continue with: 429 / 977

Advancing to step 3:
977 goes into 429 0 times with a remainder of 429.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 429 and we're left with 429.
Take the next digit (5) from the dividend and append it to 429, then repeat: 4295 / 977

Going ahead to step 4:
If we divide 4295 by 977, we get 4 and a remainder of 387.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 3908 from 4295 and we're left with 387.
Take the next digit (5) from the dividend and append it to 387, then repeat: 3875 / 977

Moving on to step 5:
977 can be fit into 3875 3 times, resulting in a remainder of 944.
Write down 3 as next digit of the result. 
Result so far: 43.0
Subtract 2931 from 3875 to get 944.
Take the next digit (1) from the dividend and append it to 944, then repeat: 9441 / 977

Let's proceed to step 6:
977 can be fit into 9441 9 times, resulting in a remainder of 648.
The number 9 becomes the next digit in our result. 
Result so far: 439.0
Deduct 8793 from 9441 and we're left with 648.
Bring next digit (4) of the dividend behind the 648 and repeat the process: 6484 / 977

Advancing to step 7:
When dividing 6484 by 977, we get 6 with a remainder of 622.
Record the quotient 6 as the next digit in the result. 
Result so far: 4396.0
The remainder is 622 after subtracting 5862 from 6484.
Append the next digit (6) from the dividend to 622 and continue with: 6226 / 977

Moving on to step 8:
6226 divided by 977 is 6 with a remainder of 364.
Put 6 as the next digit of the answer. 
Result so far: 43966.0
If we subtract 5862 from 6226, we get 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Going ahead to step 9:
3640 divided by 977 is 3 with a remainder of 709.
The number 3 becomes the next digit in our result. 
Result so far: 43966.3
Deduct 2931 from 3640 and we're left with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Step 10:
When dividing 7090 by 977, we get 7 with a remainder of 251.
Record the quotient 7 as the next digit in the result. 
Result so far: 43966.37
Subtract 6839 from 7090 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Step 11:
The number 977 fits into 2510 2 times, leaving a remainder of 556.
Use 2 as the next digit of our solution. 
Result so far: 43966.372
Subtract 1954 from 2510 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

On to step 12:
When dividing 5560 by 977, we get 5 with a remainder of 675.
Record the quotient 5 as the next digit in the result. 
Result so far: 43966.3725
If we subtract 4885 from 5560, we get 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6750, and continue the process.

Step 13:
977 goes into 6750 6 times with a remainder of 888.
Write down 6 as next digit of the result. 
Result so far: 43966.37256
If we subtract 5862 from 6750, we get 888.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8880, and continue the process.

Step 14:
If we divide 8880 by 977, we get 9 and a remainder of 87.
Record the quotient 9 as the next digit in the result. 
Result so far: 43966.372569
Deduct 8793 from 8880 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 15:
If we divide 870 by 977, we get 0 and a remainder of 870.
Record the quotient 0 as the next digit in the result. 
Result so far: 43966.372569
Deduct 0 from 870 and we're left with 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8700, and continue the process.

On to step 16:
8700 divided by 977 is 8 with a remainder of 884.
Put 8 as the next digit of the answer. 
Result so far: 43966.37256908
Subtract 7816 from 8700 to get 884.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8840, and continue the process.

In conclusion, the division gives 43966.37256908 with a balance of 8.84e-07.
